The Rays have released DH Jack Cust, Roger Mooney of the Tampa Tribune reports (on Twitter). Cust signed a minor-league deal with the Rays on February 17. He played for Triple-A Scranton (Yankees) and Las Vegas (Blue Jays) in 2012. He last appeared in the majors with the Mariners in 2011, hitting .214/.344/.329 in 225 at bats.

Infielder/outfielder Cody Puckett has been traded from the Reds, with whom he has spent his entire career, to the White Sox, Puckett himself tweeted. In return, the Reds will receive a player to be named later, tweets John Fay of the Cincinnati Enquirer. Splitting last season between Double-A and Triple-A, Puckett saw time in the infield (mostly at second) and corner outfield, and hit .233/.306/.390 with 16 home runs over 488 plate appearances.

The Marlins released left-handed pitcher Kevin Gelinas, tweets Matt Eddy of Baseball America. Gelinas, just 23, was Baseball America's Independent Leagues Player of the Year last season, Eddy notes.

The Rangers released catcher Konrad Schmidt, a 28-year-old who has 17 total plate appearances in the big leagues, reports T.R. Sullivan of MLB.com. Texas claimed Schmidt off waivers from the Diamondbacks last fall and then outrighted him to Triple-A in December.
